【Abstract】 A 5kW simulated generator is changed to a new one by remanufactured some parts of its shaft on the basis of the analysis of its torsional vibration properties. A software package(TVAP—M) used toanalyse torsional vibration properties of a shaft is made, which can perform a lot of functions, such as time—domain sampling, fast Fourier transform, correlation and power spectral analysis, frequence response function analysis and vibration model shape. A set of experiments is finished and the result shows that the new set of generator is useful in a mechnical——power system coaction experiment and the TVAP——M software package is practical and precise.更多还原
